BENJAMIN B. BROYLES, OF FREEDOM, TENNESSEE.

Specification forming part of Letters Patent No. 128,702, dated July 9,1872.

To all whom it may concern:-

Be it known that I, BENJAMIN B. BROYLES, of Freedom, in the county ofWashington and State of Tennessee, have invented a new and valuableImprovement in Middlin gs and Grain Feeder; and I do hereby declare thatthe folv is a plan section of the piece D.A

This invention has relation to grain or middlings feeders formillstones, and consists in the construction and novel arrangement of anapparatus through which the grain is conducted from the hopper to thestones, and which operates to scatter said grain in the proper mannerfor grinding, and is furnished withmeans of adjustment for theregulation of the feed according to the speed of the stones, al1substantially as hereinafter described.

In the drawing, Al represents a hopper, through which passes a verticalshaft, B, armed with beaters C to loosen and draw the grain down towardthe stones. At its lower end saidshaft is attached to a transverse orhorizontal piece, D, arranged within a funnel or feeding-box, E,constructed with two short tubes, F, depending from opposite sides ofthe piece D. These tubes pass into and are hinged to extensions Gr. Saidtubes, together with the extensions Gr, diverge from their upper totheir lower ends. The extensions, be ing hinged, may be brought towardeach other at their lower ends for the purpose of being inserted in theeye of the stone, after which, the bottom of the box E being placed onthe balance-rim, said extensions spread apart above the face of thelower stone. The whole of the apparatus, with the exception of thehopper A and the regulating-tube H, rotate Vwith the upper stone. Thegrain or middlings passes down through the hopper-tube, and runs off oneither side of the piece D into the tubes F, and thence to the stones.The piece D is to be made of highly-polished metal, to

which'nothing will adhere. The sides of said piece are parallel. Theupper surface is formed with convex inclines d, located at either endand on opposite sides of the piece D. The side terminations of saidinclines are respectively at the ends of the piece D, and at curvedshoulders concentric with the shaft B. The grain or middlings escapingfrom the lower end of the regulating-tube runs down these inclines,which, it will be noticed, conduct directly to the tubes F. The tube H,which is raised or lowered to regulate the feed lto th'e tubes F, andfor such purpose is furnished near its upper end with loops h, is

also provided with a curved wing, h', projecting near its lower end, andadapted to push the grain or middlings toward the inclines leading tothe tubes F, and thus keep the lower end of the tube H clear. The wingor arm h', besides being curved, is placed at an angle so as to pressdownward. When the regulating-tube is properly adjusted some convenientmeans must be employed to. retain it in position. The loops n offerconvenient facilities for coupling any supports.

To prevent the accumulation of grain or middlings around the base of thefunnel E the mouths of the tubes F are so shaped as to leave no ledgesor resting places in the way of the grain or middlings. The sides of thetubes nearest the piece D are therefore liattened and made ilush withthe sides of said piece. The outer sides of the tubes coincide with theform of the funnel E. The upper parts of the extensions Gr coincide withthe tubes F. In this way the iiat surfaces serve as a lock to preventthe tubes G from being brought closer together than necessary. The lowerends Vof the extensions may be either circular, oval, o1' otherwiseshaped, as desired.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The feeding apparatus for millstones, having the hopper A, shaft Bwith arms C, piece D with incline d, and funnel E with depending tubesF, all constructed and combined substantially as and for the purposespecified. Y

2. The vertically-adjustable regulating-tube H, having the Wing h 7 incombination with the hopper A, funnel E, and tubes F, substantiallly asdescribed.

3. The extension tubes Ghin gedto the tubes F of a mi11stone-feeder7a11constructed substentially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two Witnesses.
